Why the Universe Needs Dark Energy

Season 2 Episode 27 | 9m 33s

We know the universe will continue to expand forever, so now we can begin to complete the first Friedmann equation, and determine the shape and geometry of our universe. At first glance, it would seem that the equation doesn’t quite add up, and that our universe is a hyperbolic plane. But when we add in the cosmological constant, the equation balances out, and we return to a flat universe.

Extras
All particles belong to two large groups: fermions and bosons.
Just how much stronger is this year’s solar activity going to get?
So you’ve decided to jump into a black hole...
We only recently figured out where cosmic rays are coming from.
Black hole complementarity may force us to rethink what it means to say that it exists.
To travel the stars without faster than light travel we’re going to need a generation ship.
Today we are jumping into a black hole. Again.
The Moon: humanity’s first destination beyond our atmosphere.
So how did humans figure out the solar system? Eclipses!
Is gravity just an emergent effect of entropy?
